Vphotographic copying apparatus are known, such apparatus are deficient in one or more respects in that their speed of operation may be comparatively slow, the sequence oi' the records handled and copied may be changed, the records may not be continuously fed into or removed from the respective feeding and discharging stations, and/or interruptionof operation seriously affects or elim- A inates the photographic copying. Another outstanding fault of known apparatus is that the feeding means and photographic copying machine are arranged so that the records can not be fed from the bottom of a stack, leaving the top of the stack free for addition of other records, without complicating the feeding means or operation of the photographic copying machine.

The primary object of the present invention is the provision of a record handling and photographic copying machine capable of high speed operation without disturbing the sequence of the records and having automatic controls responsive to a predetermined condition so that operation of the apparatus may be interrupted without affecting the photographic copying of the records.

Another object of the invention is the provision of a record handling and copying apparatus including a feeding means which may be stopped and including a control means whereby the opermanual operation, to an auxiliary film windingv cycle, to improper spacing or absence of records from the feeding means, to an abnormal condition of the camera in the copying machine and/or to a full condition of the record receiving means whereby the feeding means is first rendered inoperative to stop the feeding of records and then 30, a stack with their record bearing face downward 2 the copying machine is shut down only after all of the records therein have been properly photographed.

A st ill further object is the arrangement of a feeding means including a feeder and conveyer with common drive means with respect to a copying machine having a drive means operating in synchronism with said common drive means and whereby said feeder, conveyor, and common drive means may be adjusted or inspected and conveniently stopped prior to shut-down of the photographic copying machine which continues to operate until all of the records therein have been photographed.

Other and further objects of the invention will a be suggested to those skilled in the art by the following description.

'Ihe aforementioned and other objects of the invention are embodied in a record handling and photographic copying apparatus which comprises generally a feeding means, a photographic copying machine, a receiving means, and a plurality of controls responsive to a predetermined condition andoperating first to interrupt the feeding means and then to shut down the copying machine only after the records therein have been photographed and preferably discharged. Said feeding means is composed of an intermittent feeder for removing records from the bottom of and of a conveyer having an arcuate path and for moving the records from the feeder and'delivering them to the copying machine with their record bearing face upward. The copying machine is preferably of the continuous type and in which the records or documents are moved continuously through a photographic field and in which the sensitized film is moved continuously in an exposure position in a photographic camera. A common drive means, preferably 4a synchronous motor, is operatively connected to said feeder and conveyer and a second drive means, also preferably a synchronous motor, is connected to drive the copying machine in synchronism with the feeding means. 'Ihe receiving means includes a platform, a follower plate and an abutment for accepting records from the copying machine and arranging them edgewise upon the platform with their record bearing face toward the front of the pack. The control means is responsive to manual operation, auxiliary film winding, and abnormal condition in the feeding or receiving means or in the camera and is prefcrably a control circuit including yswitches for. interrupting the same under any of said conditions and for maintaining an operating circuit for the common drive means or motor for the feeding means. Interruption of said control circuit also interrupts the operating circuit for the common drive means and establishes a second control means or circuit which is adapted after a predetermined interval or after all records have been photographed in the copying machine to stop the driving means or motor of the copying machine. While the record handling and copying apparatus of the invention is illustrated and described with respect to the handling and copying of cards for an-accounting machine of thel Hollerith type, it should be understood that the invention is equally applicable to be used in the handling and photographing of other types oi' records, such as checks, letters, bills, and etc.

In the illustrated embodiment of the invention the photographic copying machine may assume any' of the several known forms but is preferably of the continuous type. Said copying machine is enclosed in a casing provided with an opening at the front upper portion thereof and includes a four-legged standard I l, side walls i2 and i3 each provided with a hinged door I4, a top crosspiece i5. and a hinged rear cover i8. At the front of the machine the casing is provided with a pair of brackets i'l'supporting a horizontal ledge i8. The documentfeed of the copying machine includes a rotatable member preferably in the form of a drum i9 having axially spaced document en gaging surfaces 20, preferably made of cork, and rotatably mounted by ball bearings 2| on a shaft 22. Brackets 23 mounted on side walls i2 and i3 support a guide shield 24 which carries forwardly extending and upwardly inclined guide strips 2B and also a pair of bearing blocks 28. A shaft 21 is journaled in said blocks 26 and carries two rollers 28, see Fig. 5, one engaging the document engaging surfaces of drum i9 to one side of the document path and the other engaging a fiber band 29 in one of the document engaging surfaces 20,' the second mentioned roller 28 providing a friction drive to the back of the document being fed onto the drum i9. A transparent strip 30 preferably of glass is mounted in the casing adjacent the document engaging surfaces 20 of drum I 9 and holds the documents against the drum surface during copying in the photographie field. The document path of the copying machine from said photographic field consists of the document engaging surfaces 2li on the drum i9 and a plurality of rollers 8i mounted on the back of arcuate guide plates 32 and spring pressed through openings therein by springs 33 against said surfaces 20. The arcuate guide plates 32 are munted by means of screws 34 upon side plates as" fastened to the side walls i2 and is by bolts mi threaded into reinforced portions 85 of plates Bil.` The entrance to the document feed of the photographic copying machine is thus provided between the surfaces 2li on drum i9 and the guide strips 26 and is located adjacent the opening in the casing for the copying machine.

The aforementioned document field may be illuminated in any known manner but is preferably illuminated by a bank of incandescent lamps 3l mounted in sockets SB and within a metal housing having fixed side walls 89 and a fixed back wall di! which is provided with an exposure slot di. An arcuate reflector d2 is mounted upon a bracket d3 hinged at d6 to said back wall d0 and normally spring pressed into the position shown. For removal or insertion of incandescent lamps 31 the reflector i2 may be moved upwardly and is then returned to its operative position in which it directs the light from the lamp bank into the photographic field. The outstanding advantage of this arrangement of the lamp bank and reflector is that the lamps are mounted in the upright position without appreciably reducing the illumination at the photographic field `and since the lamps 3l are being burned in the position for which they are designed the normal life ofthe lamps is obtained. It has been found from experience that burning the lamps in an inclined position considerably shortens their life.

The camera H5 is of standard construction having a supply film roll 6B. a take-up roll il and an 'objective lens d8. A lm strip F extends from the supply roll 48 to the take-up rolls 4l over a drum lil and said camera 45 is equipped in the usual manner with a normally open switch 50 adapted to be closed unless the camera it is in proper position and normally open switches 5i, 52 and SB adapted to be closed respectively when the supply film roll 66 is depleted, when the takeup film roll dl is full. and when there is loss of tension in the film strip F extending between rolls 4B andrei.

The driving means for the copying machine comprises a motor lill, preferably of the synanni tion of the copying machine is not unusual and documents introduced into the entrance of the document feed or between drum |9 and guide strips 25 with the record bearing face upward will be photographed at considerable reduction onto the film Fin the camera 45.

The feeding means broadly comprises an intermittent feeder and a continuous conveyer with an arcuate path, both mounted upon a carriage also carrying a common drive means for the feeder and conveyer. Such carriage comprises a front cover 68 preferably'connected by a hinge 89 to the top cross-piece I8 of the casing for the copying machine and supporting a feeder frame l0.

The supply hopper of the feeder is formed by a front wall 8| of frame 60 and carrying polished tracks 62, -by side walls 68 and by rear uprights B4 also having polished surfaces. The feeder frame 60 has a document supporting platform 88 on which a stack of documents 88 may be placed and a cover weight 91 is placed on top of'the document stack 86 'in the usual fashion. Said document platform 88 is provided with a pair of guideways 68 for feeder heads 89. A picker assembly comprising a knife 10 mounted on a bushing 1| is rotatably fastened to feeder head 69 by'a swivel 12. An arm 13 is pivotally mounted on a Ibracket 14 of feeder frame 80 and has a slotted free end engaging ats 15 on a rod 18 extending through an opening 11 in the feeder head 69. A crank shaft 18 carries crank pins 19 and a connecting rod 80 extends between crank pin 19 and arm 13. Said crank shaft 18 also carries a cam 8| for a purpose to be later described. A drive shaft 92 is journaled in the feeder frame 60 and carries a knob 88 for manual rotation thereof. Said drive shaft 82, see Fig. 4. carries a worm 84 meshing with a worm wheel 85 on said crank shaft 18 and also carries a pulley 86 connected by a belt 81 to the pulley of a motor 88, preferably of the synchronous type.

When the motor 88 is energized drive shaft 02 and crank shaft 18 are rotated and arm 18 and feeder head 69 are reciprocated from said crank shaft 18 through the connecting rod 80. The knives 10 of the picker assemblies on the feeder heads 69 are adjusted so as to engage the edge of only ,the lowermost document or card 68 on the platform 65 and reciprocation of the feeder head 69 by arm 13 moves such lowermost document 68 between the rollers B9 and into the guiding throat formed by the lower end of polished track 62 and by a. polished guide member 80 mounted on a post 9| on the feeder frame 80. The lower roller 89 is driven and is mounted upon a shaft |89 carrying a worm wheel |90 meshing with a worm |9| on the drive shaft 82. 'I'he swivel mounting of the picker assemblies permits aligning of the knives with the edges of the documents or cards 66 which may -be slightly curved.

The continuous conveyer has an arcuate path and receives the documents with their record bearing faces downward from the intermittent feeder just described, moves the documents continuously in spaced relation through said arcuate document path and delivers the documents with their record bearing faces upward into the entrance of the document feed of the copying machine. Said conveyer is mounted between side .plates 92 which are mounted upon and extend from the feeder frame 60 and each of which plates 92 carries a bracket 98 composed of arm 94 and a foot 95. A shaft 98 is journaled in bearings 91 and carries wheels 98 having their peripheries covered with a friction material, such as rubber. Polished and xed guide members are mounted in between said wheels 8l and between wheels 98 and side plates 92. Specifically, a polished guide member 99 has its upper end bolted to a ledge 80 of feeder frame I0, has its other end bolted adjacent bracket 14 -to said feeder frame 80 and has a cylindrical intermediate portion concentric with but slightly below the peripheries of wheels 98. Polished fixed guide members |00 also have surfaces substantially concentric with but below -the peripheries of wheels 98 and are fastened along their edges to side plates 92 by screws |0I, the left end guide member |00 is provided with recesses |02 as shown in Fig. 5 for a purpose to-be described later. A pair of idler rollers |02 are mounted upon a transverse shaft |04 journaled at each end in adjustable brackets |08 on. side plates 92.

The driving assembly of the continuous conveyer comprises a pair of endless belts extending around a series f pulleys and bearing against a part of the periphery of the wheels 98. There are three pairs of pulleys, one of which is driven. A shaft |06 is journaled in bearings |01 mounted in side plates 92 and carries a pair of pulleys |08 freely rotatable on shaft |06 between colf lars |08 and in spaced relation on shaft |08 in alignment with wheels 98. A worm wheel |09 is mounted upon one end of shaft |08 and meshes with a worm I0 on the end of drive shaft 82 anda sprocket is mounted on the other end of said shaft |08. A shaft ||2 is mounted within slots ||8 in arms 94 and an adjustable screw ||4 extends through arm 94`into the slot Il! with its end abutting against said shaft ||2. The pulleys I6 are also freely rotatable on shaft 2 between collars I8 in alignment with pulleys |08 and wheels 98. A stay rod ||6 is connected between the outer ends of the arms 84. A shaft ||1 is journaled in :ball bearings ||8 which are slidably mounted within elongated slots ||9 in extensions |20 of the arms 94. Set screws i2| extend through extensions |20 into slots ||9 to engage the outside of ball bearings ||8 and to urge said ball bearings |8 against springs, not shown, within slots H9 and extensions |20. A pair of pulleys |22 are pinned to shaft ||1 in spaced relation thereon and also in alignment with the wheels 98 and the other pulleys ||5 and |08. A pair of endless belts |23 each encircle said pulleys |08, ||5 and |22 with `the belt run between pulleys |08 and |22 bearing against the peripheries of wheels 88 to form a circularor arcuate document path within the continuous conveyer.

The common drive means for the intermittent feeder and continuous conveyer includes the shaft 82 and the worms thereon for driving the crank shaft 18 of the feeder and the shaft -|08 of the conveyer. The conveyer drive also includes a spocket |24, an endless chain |25 which enl circles sprockets and |24 and which is tensioned by an idlersprocket |26 rotatably mounted in a-ball bearing |21 on the end of an arm |28 pivoted on a side plate 92 and urged by a coil spring |29 to press idler sprocket |26 and the endless chain |25 in a clockwise direction as viewed from Fig. 6. Thus, the endless belts |28 are driven only at one point or by the pair of pulleys |22 and the belts |23 are placed under tension in those portions contacting wheels 98 or the record 68, the return and inactive run of the belts |23 including any slack that may be therein. A sheet metal housing |30 is mounted upon a side plate 02 and encloses the chain drive Just described of the continuous conveyer.

The carriage assembly including the feeder, conveyer and common drive means therefor, fills the opening in the casing of the copying machine and being hinged at 59 may be readily swung upwardly for inspection, adjustment and/or repair of the feeder, conveyer and/or document feed of the copying machine. The operative position of such carriage assembly may be varied by adjustable means comprising resilvient pads |3| mounted on the ends of screws |32 threaded into arms 34 and held in an adjusted position by lock nuts |33. The angular position of a record or card being discharged from the conveyer may be varied by either or both of two adjustments. The pads |3| may be threaded into or out of arms 94 to change the angular relation between the exit of the continuous conveyer and the entrance to the document feed of the copying machine and/or the set screws |2|' may be adjusted to change the position oi' pulleys |22 with respect to the peripheries of wheels 33 and to open or close the exit bight of the document feed of the conveyer thus varying the angular position of the record or card leaving the continuous conveyer and'entering the document feed of the copying machine between the guide strips 25 and the document engaging surfaces of drum I3.

The receiving means for the records is located adjacent the exit ofthe documentfeed of the copying machine and is adapted to accept the records consecutively without changing their sequence. Such receiving means includes a hopper i4| comprising a platform |34 having a pair of polished rails |35 and having side flanges |33 fastened to depending flanges |31 of the ledge i8. Said platform |34 is also supported by a cross member |38 fastened to bracket |1 by bolts |39, see Fig. 6, screws |40 being threaded through platform |34 and into cross member |33 with the heads' of screws |40 below the upper surfaces of polished rails |35. A follower assembly comprises a follower plate |42 having ears` |43 on which rollers |44 are mounted and a center support |45 carrying rollers |48 and having a depending portion |41 extending below platform |34 and carrying rollers |48 engaging the undersurface of said platform |34. Said follower assembly is consequently freely movable along said platform |34 with plate |42 in an upright position and said follower assembly is biased or normally urged toward the periphery of the document feeding drum in a well understood manner, preferably by a weight, not shown herein. As a result, said follower plate |42 is normally urged against the document engaging surfaces 20 of drum i9 or against a record or card therebetween.

An abutment means for the records or cards is positioned within the receiving means to engage the leading edge of such records and to arrange them in edgewise relationship within the receiving hopper |4|. Such an abutment comprises polished flanges |49 mounted by screws |50 on the side flanges |38 of the receiving hopper and spaced from the card engaging surfaces of polished rails |35 a distance corresponding to the dimensions of the records in their direction of travel throughthe apparatus. The records 8B, as shown, are moved width-wise through the copying machine so that the spacing of the abutment or flange |49 above the rails |35 will be slightly more than the width of said record-s 83. For the purpose of insuring removal of the record from the document feed of the copying machine the drum i9.

The operation of the receiving means will now be described. The distance from the document feed'exit or last roller 3| to the contact between follower |42 and document' engaging surfaces 20 of feeding drum is is less than the width of the records or cards 6 6 and the records being discharged from the document feedof the copying machine will engage the surface of upright follower plate i 42 or the surface of the preceding record which is maintained in upright position by the ,follower assembly. The bias on the follower assembly holds the record against the document engaging surfaces 2i) of feeding drum i9 so that there is a tendency drive of the document upwardly between the edges of `stripper arms il and the follower plateI |62 or the last card of the pack stacked edgewise on polished rails B35. When the leading edge of the record abuts against flange |43 the tendency drive is overcome and the record is held in that position between stripper arms ll and follower plate M2 until the next record comes along. Each succeeding record moves the follower plate outwardly and when the receiving hopper Ml is full the depending portion |41 of the follower assembly will abut against the plunger |52 of a normally closed switch |53 to open the same. The function of said switch |58 will be explained later.

In a record handling and photographic copy ing apparatus operating at high speed, of the order of 400 records or cards per minute, it is very necessary that several automatic controls be provided so that the apparatus will be shut down upon the occurrence of any abnormal or undesirable condition so that such condition may be corrected. On the other hand, the very nature of a photographic copying machine, particularly of the continuous type. makes it very desirable to complete the photographic copying of all records in the machine to avoid improperly exposed copies, partial images of documents, etc. Therefore, the control system of the invention is established so that upon the happening of any predetermined condition, including manual shut off of the machine, the feeding means will be stopped immediately but the copying machine will continue to operate until all the records therein` have been photographed.

The aforementioned sequential control is accomplished by control means responsive to manual operation and/or to a predetermined condition of the feeding means, copying machine, auff-1 iliary film cranking means and/or document receiving means and is arranged or adapted first to stop the feeding means and subsequently to stop the copying machine only after all records therein have been photographed. Such control means may consist of two systems, one responsive to the aforementioned conditions and for interrupting operationl of the feeding means and the other responsive to stopping of the feeding means and for shutting down the copying machine after all the documents have been photographed. Said other control means may operate to shut down the copying machine after a predetermined interval or may be responsive to an absence of records in the document path from the photographic field of the copying machine. As shown, the control means supervises two driving means. one for 9 the copying machine and the other for the feeding means and arranged so that the controlling means responsive to a predetermined condition including manualoperation interrupts the driving means for the feeding means and the other control means which is operative only after all documents have been photographed in the copy'- ing machine to interrupt or render inoperative the driving means for the copying machine.

The primary control means which is responsive to the various predetermined conditions is preferably provided as a control circuit including kin series a relay and a plurality of switches which are normally closed but which are open upon the occurrence of a predetermined condition or manual operation, Such a control circuit is shown in Fig. 8 as follows: From the main supply line |54, connector terminal |55, wire |56. switch |51, wire |58, connector terminal |59, wire |60, either one or both of normally open switches |6| which are connected in parallel. through a normally closed manual stop switch |62, wire |63, terminal |64, normally closed switch of relay R1, normally closed switch of relay R3, normally closed switch |53, terminal |65., the coil |66 of a relay R2 operating a single pole dou-v ble throw switch |61 normally closed in one position, wire 203, connector terminal |68, wire |69, main switch 22|, terminal |10 and to the other main supply line |1|. The' relay R3 is of a standard type which requires manual resetting after it has once been energized and opened for reasons to be explained later.

The copying machine is preferably provided with an auxiliary tllm advancing means for winding a predetermined length of film through the camera for the purpose of winding a leader or nlm exposed while loading the camera onto the take-up and also for winding a predetermined length of lm or trailer onto the take-up prior to opening of the camera. Such auxiliary winding means may be automatically operated and may be constructed as shown in Schubert U. S. Patent No. 2,161,391, granted June 6, 1939. Such a film winding means is illustrated in Figs. 3 and 8 and comprises a winding motor |12 driving a worm gear 223 meshing with a worm wheel 224 which is mounted for co-axial rotation about the lm winding shaft 222. Worm wheel 224 is connected through a second one-Way clutch 225 to lm winding shaft 222 and carries a spur gear 226 meshing with and driving a timing gear 221 on shaft 228. A pinion gear 229 is mounted to rotate with timing gear 221 and drives a second timing gear 230 rotatably mounted on a shaft 23|. Said timing gear 221 carries a cam lug 232 adapted to engage and open switch arm |13 and timing gear 230 carries a cam lug 233 adapted to engage and open switch arm |14. The winding motor |12 is connected through either of -cam operated switches |13 or |14, which are normally closed as by a spring |13', and through a single pole double throw switch |15 which is automatically moved from one position to the other by respective opening or closing of the rear cover |6 of the copying machine and to the main supply line |1|. Said switch |15 is normally moved to the position shown in Fig. 8 by a spring |15' and a plunger |15" is actuated upon movement of cover i6 to closed position and moves said double throw switch |'15 to its other position which is indicated `by dotted lines in Fig. 8. In operation when said cover I6 is closed, switch |15 is moved to complete the circuit through cam operated switch |13 and Winding motor |12, such winding operation being interrupted after a predetermined length or leader of film has been wound through the camera by opening of said cam operated switch |13 which is accompanied by closing of the cam operated switch |14. When the cover I6 is open the switch |15 will be returned to the position shown in Fig. 8 whereupon winding motor |12 is again energized to wind a length of nlm or trailer through the camera of the copying machine until cam operated switch |14 is open. As shown,-the timing gears 221 and 230 carrying cam lugs 232 and 233 for operating said switches |13 and |14 may be such as to provide for winding .one length of nlm for the leader and another length of film, preferably longer, for the trailer. According to the invention the coil of relay R1 is connected In parallel with winding motor |12 and so as to be energized and de-energized therewith upon the aforementioned operation of switches |13, |14 and |15. Since the switch of relay Ri is in the control circuit, said switch of the relay Ri and said control circuit will be closed when the coil of R1 is deenergized or when the auxiliary film winding means is inoperative and said normally closed switch of the relay Rr and the control circuit will be open when the coil of said relay Ri is energized or when the auxiliary film winding mean-s is operating.

The automatic control circuits for the camera of the copying machine are preferably of low voltageQ and a transformer |'16 has its primary winding |11 connected at one side by a wire |18 to the connector terminal |68 and its other side connected through a wire |19 to a connector terminal |80, a wire |8|, connector terminal |59, wire |68, switch |51, wire |56 and terminal |55 to the main supply line |64. The secondary winding |82 of transformer |16 has one side connected by a wire |83, connector |84 through the coil of a normally closed relay R3 to ground, the other side of the secondary winding |82 being connected through a terminal |85 to one side of switches 50, 5|, 52 and 53, the other side of said switches being connected to ground. As before described, said switches 50, 5|, 52 and 53 are normally open but switch 50 is closed unless the camera 45 of the copying machine is located in its proper position and switches 5|, 52 and 53 are closed when there is an insufcient film supply on roll 46, when take-up roll 41 is full, or when there is no tension on the film F within camera 45. As a result, when camera 45 is improperly located or when there is an undesirable film condition therein the circuit is closed through the secondary of transformer |82 and the coil of relay R3 is energized to open the normally closed switch of said relay R3, which switch is in the aforementioned control circuit. At the same time an audible or visual signal |86 may be energized to warn the operator that there is an undesirable condition with respect to the camera of.

the copying machine.

An automatic control is provided to stop the feeding means when there are no records or cards in the document path of the conveyer or when the records or cards are improperly spaced in said conveyer. Such a control means is shown in some detail in Figs. 5 and ,'1 and preferably comprises a pair of bell cranks |81 pivotallv mounted by screws |88 on studs |92 on side plate 92. see Fig. 5, one arm of each bell crank |81 proiecting through the recess |02 in polished guide member and into the document path of the conveyer, the other arms of each bell crank |81 being will be closedwhen properly spaced records t8 are moving through said document path and so that both of said switches iSi will be open if there is improper spacing between said records et lor if there are no records 8@ in the document path of the conveyer. Specifically. said bell cranks |81 extend into the document path at a spacing of approximately one and a half card pitches from each other. As a result of this ar1 rangement of bell cranks iii'i and parallel con nection of normally open switches iti it will be evident that both switches will be open to interrupt the aforementioned control circuit when there are no cards in the documentpath of the conveyer or when the cards therein are improperly spaced or too far apart.

The common driving means for the feeding means includes feeding motor t@ as has already been described and such common driving means is rendered operative or inoperative by closing or interruption respectively of the aforementioned control means or circuit. The operating circuit for said. common driving means includes said feeding motor 8B which has one side connected to wire |80 which may be traced bach to the main supply line |54 and the other side of motor 8d is connected by a wire |83, terminal |94 through switch |81 of the relay Rn when the coil |88 thereof is energized to terminal i8@ whichmay be traced to the other main supply line |1i'. Consequently, when the primary control circuit is closed coil |88 of relay Rr is energized and switch |81 thereof is moved to close the circuit through feeding motor 88 whereupon the intermittent feeder and continuous conveyer will be operated in a manner already described. On the other hand, interruption of the control circuit by opening of any'oi.' the switches therein will de-energize the coil |88 of relay Rz and switch |81 will be opened to render inoperative the feeding motor 88 oi' the common driving means for the feeding means.

Since the record controlled switches |8| are both open when there are no cards in the continuous conveyer, or when the cards therein are improperly spaced, it is not possible to complete the primary control circuit and thereby complete the circuit for feeding motor 88 to start the intermittent feeder and conveyer and bring cards into position to close one of switches 8|. Consequently, a normally open starting switch |85 has one side connected to wire |83 of the control circuit and the other side connected through a Wire |98 through terminal |55 to the main supply line |54. Closing of said starting switch |95 will short-circuit the record or card operated switches |8|' so that relay Ra may be energized and the operating circuit for feeding motor 88 completed.

The driving means for the copying machine includes the motor 54 which is mechanically connected as already described to the feeding drum |9 and camera 45 of the copying machine and i2 of motor 54 is controlled by the closing and opening of switch |81.

In its broadest aspect the invention contemplates any means or arrangement which initiates a cycle upon stopping of the feeding means and during 'which the copying machine remains operative until ali records have been photographed. Specifically, two forms of such a control means are shown, one an interval timer for opening the operating circuit of motor 5d at a predetermined interval after its energization, and

the other a relay coil energized to open said switch |51 after all documents have left the document feed leading from the photographic neldof the copying machine.

Said control means may be provided as a control circuit including an interval timer m9 of known form and including timer motor 28d having one side connected through wire |88 and terminal |55 to main supply line |86 and having its other side connected through a terminal Ztl and wire 292 through switch itl, in its normally closed position when the coil |88 of relay Re is cie-energized, and through wire 283, terminal |88 thence to the main supply line, i1 i. The interval timer it@ is set or arranged in a known manner so that after a predetermined interval following energization of timer motor 2t@ the switch |81 is opened, being closed immediately thereafter. Such opening ci switch |81 not only interrupts f the circuit to motor iid but also interrupts the which is electrically connected at one side by a primary control circuit and the operating circuit for the feeding motor 88 so that it is not possible to operate the feeding means unless the copying machine is also operating.

A counter means is provided to indicate the num.- ber of records passing through the record handling and photographic copying apparatus and may be associated with any available part of the apparatus but is preferably associated with the intermittent feeder and rollers 89 and guide member t@ adjacent thereto. Such a counter means comprises a normally open switch 206 having a movable contact member which is operated by a spring wire feeler 208 centrally pivoted in a lug 208 on a plate 201 attached to the front wall 8| of the feeder frame 80. The upper end of feeler 205 is connected to the movable member of switch 204 while the lower end 205' is circularly bent and normally extendsinto the record, path between the intermittent feeder and guide member 90. A normally open micro switch 208 has a plunger 209 and carries a leaf spring 2|0 extending into the path of cam 8i on the crank shaft 18 of the intermittent feeder, said cam 8| being designed to operate leaf spring 2|0 and plunger 209 to close switch 208 during one-half revolution of crank shaft 18 and then to open switch 208 during the other half of a revolution of crank shaft 1B. A magnetic counter 2|| of standard construction is mounted upon cover 58 and includes a solenoid 2|2 which for each energization moves the counter one unit. Said normally open switch 204 and micro switch 208 are connected in series with solenoid 2|2 which has its other side connected by a wirel 2|3 to the connector terminal |10 on the line side of main switch 22|. The other side of such counter circuit is connected by a wire 2|4 and wire |98 to the connector |55 and other main supply line |54. During a counting cycle the micro switch 208 is closed for half of the cycle and open for half of the cycle, such opening giving the ratchet or other member in the magnetic counter 2|| time to retract or re-set for the next cycle. The

13 normally open switch 204 is closed only when there is a card passing between rollers 89 and through guide member 90 so that even if the intermittent feeder is operating without any records or cards in the hopper thereof the counter will not be operated merely by opening and closing of the micro switch 208. In other words, in order to get a count, switch 208 must be closed by operation of the feeder and switch 204 must be closed by the presence of a card between the rollers 89. t should be noted that the counter circuit is connected on the line side of all controls or switches so that automatic or manual operation of the control does not necessarily deenergize solenoid 2I2 and cause a fallacious count, for instance, when the main switch 22| is opened and closed or when operation of the feeding means and copying machine is caused by any of the automatic controls.

The alternative control for interrupting the drive means of the copying machine after all records have been photographed therein may comprise a pair of normally closed switches 2|5 connected in series and mounted upon a suitable bracket 2|5 within the casing of the copying machine. Apair of supports 2 |1 are also mounted on bracket 2|6 and have ears 2|8 in which Wire feelers 2| 9 are pivoted. Said feeiers 2|9 have curved ends extending through spaced openings in an arcuate guide plate 32 adjacent the document discharge path of the copying machine. Said upper ends of the feelers 2|9` may extend into the space between the axially spaced document engaging surfaces 20 of the drum I9 whereupon the other ends of feelers 2 9 permit switches 2|5 to be normally closed. When a record or records in spaced relation move between drum I9 and guide plate 32 one or both of feelers 2|9 will be operated to open one or both of normally closed switches 2|5 and conversely when there is no document between drum |9 and guide plate 32' both of feelers 2|9 will be moved to the position shown and both of switches 2 I 5 will be closed. The control circuit for this modified form of the invention extends from the terminal 20| through switches 2|5 and through the solenoid 220l which is adapted to open the normally closed switch |51. Thus, when switches 2| 5 are both closed solenoid 220 will be energized to open switch |51 and interrupt the operating circuit of the motor 54 for the copying machine.

The operation of the record handling and photographic copying machine is as follows: The

The records 55 are fed with their record bearing face downward between rollers 89 and the passage of each record through the guide members 90 actuates feeler 205 to operate the magnetic counter. The documents from guide members 90 are fed between rollers |03 and belts |23 and between the periphery of wheels 98 and belt/s |23 through the arcuate path of the continuous conveyer which discharges the records with record bearing faces upward into the entrance of the document feed of the copying machine. The records are moved through the copying machine l and photographed therein in a well understood manner, the records being moved continuously on the drum |9 and the film being moved continuously in the camera 45 and the records leaving the photographic field of the copying machineare delivered into the receiving means in a manner already explained. As soon as the first record closes one of the switches |5| the primary control circuit will be maintained therethrough and the starting switch may be released to return to its normally open position without interrupting operation of the machine. However, if for any reason the records 55 or cards are improperly spaced in the continuous conveyer or are not passing through the continuous conveyer then both of switches |9| will be opened to interrupt the control circuit, cause interruption of the operating circuit for the feeding motor 88 and then after all of the documents have been photographed interrupting the circuit for the motor 54.

The interruption of said primary control circuit may be caused by the happening of any one of several predetermined conditions. For instance, the normally closed switch |52 may be operated or opened. The camera 45 may be improperly located in the copying machine so that switch 50 is closed to energize the coil of relay Rs and open the switch thereof. The iilm supply may be depleted, the take-up film roll 41 may be full or there may be lack of tension on the iilm in the camera 45 to cause any one of switches 5|, 52 or 53'to close, thus again energize the coil of relay Rs and opening the switch thereof. Inasmuch as the abnormal condition in the camera 45 may only occur intermittently such as an eccentric winding of the iilm on the take-up nlm roll 41 causing intermittent closing of the corresponding switch 53, relay Rs is preferably of the manual re-set type so that once the switch of relay Ra is open it must be re-set before the primary control circuit is again completed. The use of a manual re-set relay Ra prevents resumption of operation in the event of a temporaryA correction of the illm condition in or location of the camera t5. The receiving hopper may become full so that normally closed switch H58 is opened by abutment oi depending portion itl against the plunger 862 of said switch les. The rear cover le may be opened to initiate operation of the auxiliary nlm advancing means and cause energlzation of the coil of relay Ri which .opens lthe switch thereof. Also immediately after closing of said rear cover it said auxiliary nlm advancing means is again energized with energization oi the coil of relay R1 vand opening oi its normally closed switch until the predetermined amount of illm has been wound through the camera. Any oi these conditions interrupts the primary control circuit.

Upon interruption of the primary control cir cuit the coil it of relay Ra is de-energized and switch lill moves to its normally closed position with an opening, a. photographic copying machine within said casing and including a camera adapted to contain a iilm and having a. switch and also interrupts the primary control circuit switch |81 completes the circuit through the interval timer |99 which after a, predetermined interval suillcient to photograph all of the documents in the copying machine opens switch |51 and de-energizes motor 54 to render inoperative the driving means for the copying machine. Al= tefrnatively, such closing of switch l''l may establish the secondary control circuit in the modiiied form of the invention so that after all ofv the documents have been photographed in the copying machine and switches 2|5 are closed then solenoid 220 is energized to open switch |51' and interrupt the operating circuit for motor 54 to render 'the driving means for the copying machine inoperative. As soon as the abnormal condition has been cleared the apparatus may resume y operation in the manner already described.

Under normal conditions a single operator need merely to stack records in the hopper of the intermittent feeder and remove the photographed records from the hopper oi' the receiving means and one operator may attend to two or more of these record handling and photographic copying machines because the machine automatically shuts down upon the occurrence oi any abnormal or undesirable condition and will remain so until that condition is corrected by the operator. However, such shut-down occurs in the sequence explained in that the feeding means is first rendered inoperative and then only after all records have been photographed is the copying machine stopved.
